JAR AND FASTENER THEREFOR.

SPECIFICATION f rming part of Letters Patent NO. 790,750, dated May 23,1905.

Application filed September 23, 1904. Serial No. 225,632.

To a, whom, it may concern.-

Be it known that we, JosnPH J. RANNEY and RALPH D. TINKHAM, of Monmouth,in the county of Warren and State of Illinois, have invented certain newand useful Improvements in Jars and Fasteners Therefor, of which thefollowing is a specification.

Our present invention relates to jar-closures, and particularly to thatclass or type thereof in which a spring is used to exert a first orprimary degree of pressure on the lid or cover of the jar, and therebyon the usual gasket or packing-ring, and in which other means are usedto exert a secondary or additional pressure thereon and by the use ofsuch means to provide a fastener or closure which will effectually sealthe jar and prevent its contents becoming fermented or putrescent.

Another object is to provide a jar and closure therefor which whilebeing a two-de gree-pressure fastener or closure yet will be strong,durable, economic of manufacture, efficient in use, and capable of beingused many times over.

A further object is to providea two-degreepressure closure in the use ofwhich the jars after having been filled and sealed may be compactlyboxed and shipped as to eliminate danger of breakage, to economizespace, and to prevent the working parts from becoming loosened ordisturbed, and thus permit air to enter the package and causedeterioration of the contents.

Other objects of the invention will hereinafter appear.

The novel means employed in carrying out the aforesaid and other objectsof our invention, as well as subsidiary objects, is hereinafterdescribed and made the subject-matter of the claims hereto appended. Thepreferred construction of parts and the arrangement thereof areillustrated in the accompanying drawings, in which Figure 1 is avertical sectional elevation, partly broken away; Fig. 2, a top plan,and Fig. 3 a plan of the spring and lever.

Similar numerals are employed to indicate corresponding parts whereversuch may ocour in the several figures of the drawings.

1 represents a jar having an elongated neck 2, and within the neckaforesaid is a circumferential bead 3, an annular groove 4, a verticalwall 5, and a flange 6, having a horizontal seat or shoulder 6. The bead3 is intersected by a vertical mortise or channel 7. The lid consists ofa body 8, having a pendent body member 9, a knob 10, having a groove 1Oin its face, said knob located centrally of the body portion 8, ahollowed-out portion 11, sursounding said knob, and an annularperipheral flange 12, having a flat under surface 12, corresponding inoutline to the outline of the upper face 6 of the flange 6, a beveledupper 'edge 12 and a member 12 13 represents a metallic spring oblong inform and in one of its arms has a longitudinal slot 14, having atransverse enlargement 1 F for a purpose hereinafter described. Theordinary gasket of resilient material is in all cases to be seated onthe shoulders 6 and the lid 8 placed thereupon, with the lower surface12 of the flange 12 contacting said gasket and the body member 9depending into the mouth or throat of the jar. The spring 13 is of suchform that when one of its ends is placed within the groove 4 its otheror distal endwill extend diametrically across the mouth of the jar tothe outer edge of the mortise 7, into which it is forcibly directed withits ends resting against the lower face 3 of the head 3 and itsmid-length portion contacting the knob 10. The spring is then given apartial rotation on its axis in either direction, which operation willbring both its ends beneath the head 3 and resting and held in place bythe lower face thereof, thus exerting a primary degree of pressure onthe lid, and thereby the gasket.

15 is a lever of the second order and has a longer arm 16 and a shorterarm 17. At the end of the shorter arm are trunnions 18, and on theshorter and longer arms are lugs 19 20. respectively. The spring 13being in the position shown by dot-lines at Fig. 1 and it being desiredto exert a secondary pressure on the lid and gasket, the shorter arm 17of the lever is introduced downwardly through the enlargement 1 1 of theslot 14, (or it may be introduced laterally and directly through saidslot,) with the trunnions fulcrumed in a groove or bearing 10 in theface of the knob 10, as

shown best at Fig. 1, the lugs 19 below the spring and the lugs 20 aboveit. The lever is then drawn longitudinally of the slot 14 with a slidingmovement to the farthest position, with the trunnions 18 resting in thegroove 10. The arm or handle 16 of the lever being then thrown over intothe position shown by full lines at same figure, the lugs 19 will forcethe median portion of the spring upwardly, and thus exert a maximumdegree of downward pressure upon the parts Whereon it acts. The lugs 20will prevent the spring and the lever from becoming disengaged from eachother when not in use. In this connection it may here be stated that, ifpreferred, the en largement 14: may be dispensed with. It may be furtherstated that the force exerted to bring the spring to its full-lineposition will be reactionary and will cause an effective, absolute, andpositive hermetic seal to be formed. Whenever it becomes desirable toopen the jar for access to its contents, a reversal of the hereinbeforeoperations is performed.

The. parts of the fastener are of such di- ,mensions and are soconstructed that when they are in their locked positions they lie in ahorizontal plane below that of the upper edge of the neck of the jar,and all danger of accidental displacement of the lever thereby unsealingthe jar is averted. This feature of having all moving parts in ahorizontal plane lower than that of the upper surface of the neck of thejar, thereby permitting the jars to be piled one on top of another andeach having a flat surface to rest upon when so piled, is of greatutility, as it economizes space in shipping and, furthermore, lessensthe danger of breakage.

A bail or any other preferred means of carrying the jar may be securedthereto, if desired. The closure is exceedingly simple and effective.The lever is constructed of one piece of metal, as is also the spring,and both are practically unbreakable. Every part beinginterchangeable,cheapness is attained,and although the pressure exertedis a powerful one the device may, owing to the construction of thelever, be easily manipulated.

The advantages of the invention will be apparent and the operation willbe understood from the foregoing description, it being particularlynoted that various changes may be made in the details of constructionwithout departing materially from the general idea in- Volved.

Without limiting ourselves strictly to the described form of the partsand the details of construction and arrangement shown, we claim asnew- 1.
